This part is discontinued and is no longer available.
However, for part SL163516: CRBCASE35 is a potential alternative. As this lock is discontinued, we'd recommend a replacement gearbox. If a full, replacement lock is required, a VERSA V-MPL repair lock can be used. Some adjustments will be required but it is supplied with keeps for any new locking positions.
